...ke it over the hill and wind its course to a final resting place -- its folded state. If it lacks the energy to clear the hill, it will slide back into a partially folded or misfolded state. Kiang and graduate student Nolan Harris's new approach to probing these energy states yields something akin to a map...

... uses Type 2 T helper cytokines as a signal to get resting mammary duct cells to begin dividing and differentiating to produce large numbers of milk-producing cells. These cells then release more cytokine molecules to get the body to make yet more milk producing cells. Using a mouse model, the scientists wer...

...dings indicate that the swimmers stir up pathogens resting in the sediment. The Environmental Protection Agency does not require testing for microsporidian spores, C. parvum or G. lamblia in recreational waters, because of the cost and difficulty in measuring these pathogens. Regulations do require that wa...

...e researchers identified a very small, rare set of resting cancer stem cells in the lung cancer samples that looked and behaved much like normal adult lung tissue stem cells. Both the cancer and normal stem cells were protected equally by multiple drug resistance transporters, even if the bulk of the tumor r...

... cells that line blood vessels derived from normal resting tissues, regenerating tissues, and tumors. A comparison of the normal vessels revealed several organ-specific endothelial genes that could potentially aid in the delivery of molecular medicine to specific anatomical sites. The study also revealed 13 ...

...The insect respiratory system is so efficient that resting insects stop taking in air as they release carbon dioxide, according to research by Stefan K. Hetz of Humboldt University in Berlin, Germany. This allows them to keep oxygen and carbon dioxide levels in balance. Too great a concentration of oxygen is...

...arch done on proteins is based on their study in a resting state and their study in movement is extremely limited due to technological limitations. Today, a French team has made a movie of an enzyme (a protein that catalyses chemical reactions) found in bacteria. The achievement of this research is two-fold:...

...for shutting down microglia, which exist both in a resting state and an activated state. Tumors likely need microglia to be activated before they can convince them to send out growth signals. The tumor then exploits these signals to enable its rapid growth. If scientists can block microglia activation, they ...

...calcium carbonate trickles down to find its final resting place at the bottom of Lake Van. Day by day during this period millions and millions of pollen grains float down to the depths. Together with lime they form a light-coloured layer of sediment, what is known as the summer sediment. In winter the co...

...ice with acute inflammation tended to have reduced resting energy expenditure. On the other hand, mice with chronic inflammation had significantly decreased resting energy expenditure. The data also suggested that mice with acute inflammation used fat as an ...

...ally stops cell division and returns the cell to a resting state. When that braking system is faulty, uncontrolled cell division and the growth of cancer can result. Weizmann Institute scientists studied this system of brakes, and identified a number of the genes involved. According to the study's find...

...aboons, like unhealthy people, often have elevated resting levels of stress hormones. "Their reproductive system doesn't work as well, their wounds heal more slowly, they have elevated blood pressure and the anti-anxiety chemicals in their brain, which have a structural similarity to Valium, work differently...

... when the creatures are active than when they are resting in the day," Herzog speculated. "This might help them find food or mates when they are hungry for food or for love." Do the results suggest that women should splash on the Estee Lauder during the night so that men can notice all the more and shun th...

...e Lab on the Newark campus. While each subject lay resting on a gurney, various gauges, connected to computers, were placed on their arms and legs. An arterial cuff was attached to an upper arm to monitor blood pressure, and venous cuffs were placed around the upper thigh and upper arm to measure the blood f...

...rbance." Tree frogs characteristically go into a resting posture after wiping themselves, tucking their limbs tightly against or beneath their body and closing their eyes. The researchers found that this series of actions following "waxing" allows tree frogs (Phyllomedusa hypochondrialis) to limit rates of...
